NEW JERSEY, A CORPORATION OF NEW SQLE-LEVELING MACHINE.

Application filed May 21, 1908. Serial N 0. 434,042.

To all whom it may concern.

Be it known that I, EUCLID I. LA CHA- PELLE, citizen of the UnitedStates, residing at Beverly, in the count of Essex and State ofMassachusetts, have invented certain new and useful Improvements inSole-Leveling Machines; and I do hereby declare the fol- I lowing to bea full, clear, and eXact description of the invention, suchas willenable othersskilled in the art towhich it appertains to make and usethe same.

The present-invention relates to sole leveling machines intended moreparticularly for leveling the soles of turned shoes, although variousfeatures of the invention may be embodied with advantage in machinesintended for use in leveling welt shoes.

In the manufacture of turned shoes, the edge of the soleis bent ormolded away from the lip previous to the sewing of the upper to thesole, and after the shoe has been turned and re-lasted this molded edgeappears as a well defined ridge extending around the margin of the sole.lln leveling turned shoes by hand the operator removes this marginalridge by subjecting the marginal portion of the sole-to an outwardrubbing pressure with a rubstick. 'llhe final pressing andshaping of thesole is secured by subjecting the sole to a longitudinal rubbingpressure with a rubstick. i

It is the object of the resent invention to provide a machine by w ichthe sole of the shoe may be subjected to an outward rubbing pressurealong its margin, and to "a final longitudinally progressive pressuretobring it to its final shape, and by which the leveling operation maythus be quickly performed, and with as good results as are produced bythe hand leveling operation when performed by a skilled operator.

Inaccordance with one feature of the invention, the marginal portion ofthe sole is progressively acted upon by a leveling device which isforced repeatedly against the sole and is moved laterally outward overthe marginal portion while in engagement therewith. The outward rubbingpressure thus produced stretches the marginal portion of the soleoutward, thus removing the mar-- ginal ridge, and the rapid repetitionof this outward stretching pressure gives a permanent set to the moldededge, so that. it will not tend to subsequently return to its originaldistorted shape.

A further feature of the invention contemplates the provision of devicesfor si-' multaneously and progressively subjecting .the opposite sidesof the sole to rapidly repeated outward rubbing pressure. This insuresthe accurate shaping of the sole, since the lateral strains arebalanced, and each s de is held from distortion while the other side isbeing operated upon, and also increases the rapidity with which theleveling of the sole may be completed. In accordance withthis feature inits broader aspects, apy suitable form and arrangement of devicesforsubjecting the marginal portions of the sole to repeated compression andout ward stretching may be employed. In their preferred form, however,these devices consist of tools arranged to act upon opposite sides ofthe sole, and so operated that they independently apply pressure to thesole. By thus operating the tools an efiective action on each side ofthe sole isinsured, since the pressure applied to the sole byeach toolisunafiected by variations in the resistance offered by the sole to theother tool.

In leveling turned shoes it is frequently desirable that the center aswell as the marginal portions of the sole shall be subjected to repeatedcompressions while operating on certain parts of the sole, andthat themarginal portions only should be subjected to such operation whileoperating upon other parts of the sole.

Another feature of the invention accordingly contemplates the rovisionof means "for repeatedly compresslng the. center and sides of the soleand for arresting the action of said means upon the'center of the solewhile continuing the action on the sides.

A furtherfeature of the invention contemplates the provision in amachine provided with means for subjecting the sole to repeatedcompressions, of an additional levcling device for applying alongitudinally progressive pressure to the sole to smooth out and pressthe sole into final shape. By providing such a leveling device, whichacts upon the sole during the action of the compressing devices, therapidity of the leveling operation is increased, and any irregularitiesproduced by the compressing devices are immediately removed. j

The leveling device which I prefer to employ for giving the final shapeand finish to the sole is a vibrated leveling roll such as is commonlyemployed in sole leveling machines, and certain features of theinvention contemplate the provision of a novel and improved constructionand arrangement of the mechanism for varying the lateral inclination ofsuch a roll. In accordance with one of these features, the leveling rollis so mounted that the axis about which it is turned in varying itslateral inclination is shifted laterally toward the side of the sole onwhich the roll is to operate. -This enables the roll to be tipped tooperate upon the shank without materially changing the relation betweenthe sole and the bed in which the rollis carried, and is of especialadvantage in case other leveling devices are mounted upon the same bedwith the roll. In accordance with another of these features, themechanism for changing the lateral inclination of the roll isconstructed to lock the roll against displacement under the pressureexerted thereon by the sole, so that the operating lever is unaffectedby the pressure between the roll and sole tending to vary its lateralinclination.

A further feature of the invention contemplates the provision of meansfor smoothing out the heel and shaping the heel seat of the shoe, thesole of which is being leveled. This means is preferably so constructedand arranged that it will operate upon the heel of the shoe supported onthe jack during the forward and return movements of the jack, and willthus smooth out the heel and shape the heel seat during the operation ofthe leveling devices upon the sole. In its broader aspects this featureof the invention contemplates the employment of any suitable form andarrangement of means for smoothing out the heel and shaping the heelseat, which is constructed and arranged to operate upon the heel of theshoe during the leveling operation. In its preferred form, however, themeans for smoothm the heel and shaping the heel seat inclu e certainfeatures ofinvention which are not limited in their application toconstructions in which the heel seat is shaped and the heel smootheddurin the leveling operation, but

may be embodied in machines which are not provided with means forleveling the sole. The invention also includes certain fur ther featureswhich will be referred to in connection with the description of themachine in which I have embodied the invention, and will be set forth inthe claims.

The various features of the invention will be readily understood from aninspection of the accompanying drawings, in which Figure 1 is a sideelevation of a leveling machine embodying all the various features ofthe invention in the forms in which I prefer to employ them; 2 is a planview. partly in section; Fig. 3 1s a section on line a2-w, Fig. 2; Fig.4 is a detail view partly in section, looking from the side opposite toth at shown ln'Fig. 1, and showing the parts in a ditferent position;Fig. '5 is a section on line ez, Fig. 1; Fig. 6 is a section on line gy, Fig. 5; Fig 7 is a section on line 11-12, Fig. 3; Fig. 8 is a detailfront view of the compressing tools; Fig. 9 is a similar view showingthe tools in different position; Fig. 10 is a section on line u u, Fig.3; Figs. 11 to 17 are detail views showing the operation of themechanism for starting and stopping the operating mechanism for thecompressing tool; Fig. 18 is a section on line Io- 11:, Fig. 2; Fig. 19is a sectional elevation showing a modified form of means forcontrolling the action of the compressing tools; Fig. 20 is a plan viewof the devices shown in Fig. 19; Fig. 21 is an elevation looking towardthe right in Fig. 19; Fig. 22 is a transverse sectional view through theside compressing tools; Fig. 513 is a side elevation showing a modifiedconstruction in which the jack carries means for smoothing the heel andshaping the heel seat of a shoe supported on the jack; Fig. is atransverse sectional view showing the operation of the smoothinghammers; Fig. 25 is a plan view showing the arrangement of the hammers;and Fig. 26 is a detail view showing the cams for operating the saidhammers.

In the machine shown in the drawings the relative movements between theshoe supporting jack and the leveling devices for transferring the pointof operation of the leveling devices along the shoe sole are produced byadvancing and retracting the jack. The leveling mechanism comprises twocompressing tools arranged to operate upon opposite sides of the bottomof the sole, a third compressing tool arranged to-oporate upon thecenter portion of the sole, and a leveling roll, the lateral inclinationof which may be varied in accordance with the part of the sole beingoperated upon. The leveling devices are arranged and operated tocomplete the leveling of the sole during the forward and return movementof the jack. The leveling roll remains in engagement with and operatesupon the sole during the entire forward and return movement of the jack.As

the jack starts forward, the center and side. compresing tools arebrought into action, and continue in action until the shank is reached,when the action of the center tool is arrested, the side toolscontinuing to act through the shank. When the breast of the heel seat isreached by the leveling roll, the motion of the jack is reversed, and atthe same time the compressing tools are thrown out of action, so thatduring the return movement of the jack the sole is acted upon by theleveling roll only.' The roll is arranged to act upon the sole duringthe advance movement of the jack after the sole has been subjected tothe action of the compressing tools, and thus during the advancemovement bf the jack the roll acts to level and give final shape to thatportion of the sole which is operated upon by the roll during thismovement of the jack. During the forward movement of the jack, theleveling roll, as it reaches the shank of the sole, is tipped so "thatit will operate upon and fluish one side of the shank. On the returnmovement of the jack, and after the compressing tools have been thrownout of action, the leveling roll is tipped so that it will act on theother side of the'shank, and will level and finish-this side of theshank during the first part of the return. movement of the jack. Whenthe ball line is reached during the return movement of the jack, theleveling roll is tipped to act upon that portion of been properlyleveled during the advance movement of the jack.

The jack upon which the shoe is supported comprises a frame 1pivotally-supported upon a shaft 2, and provided with shoe supportingdevices 3 which may be of any, suitable construction. The jack frame isconnected by means of a link 4 with a crank 5 which is secured to acrank shaft 6. During the'operation of the machine the crank shaft 6 isgiven an oscillatory movement to adilriance and retreat the shoesupporting ae The leveling devices are mounted in a vertically movablebed 7 pivotally mounted and normally supported by a spring 9. Thedownward movement of the front end of the bed 7' is limited by-a stopnut 10 carried by a stop rod 11 and arranged to engage a pin 12 on therear end of the bed. The bed 7 may be yieldingly forced in a directionto force the leveling devices the sole of a shoe carried by the jack bythe depression of a treadle 13. The treadle is connected by means of alink 14 with a block 15 which is in turn connected by a rod 16 with thebed 7. A spring (not shown) 'is interposed between the rod and the block15 in a well known manner, so that when the treadle 13 is depressed thefront endof the a pressure dependent upon the tension of the spring bed7 is forced downward with within the block 15. The pressure exerted by"the spring may be regulatedby means of .a nut 17 mounted on the upperendof the rod 16, and arranged to engage the bed 7.

The leveling devices carried by the bed 7 consist oftwo compressingtools 18 and 19 arranged to act upon opposite sides of the sole of ashoe supported on the jack, a third tool 20 arranged to act upon thecenterportion of the sole, and a leveling roll 21 so mounted in the bedthat its'lateral inclination may be varied in accordance with theportion of the soleto be acted upon. The tools 18, 19 and 20 are carriedin a head 22 the fore part which has not into engagement with bed 7. Thecenter tool 20 v and 26 which extend up through the head 22 and are heldin normal position in the head by springs 27 and 28. The recess in thehead in which the rod 28 for the center tool is mounted is so arrangedthat the rod-23 is substantially perpendicular to the surface of thesole upon which the center tool acts. The recesses in which the rods 25and 26 carrying the side tools are mounted, converge laterally towardthe sole, as indicated in Figs. 8 and 9. The side tools 18 and 19 arepivotally mounted on the lower ends of the rods 25 and 26, so that theymay rock laterally, and automatically conform to the lateral curvatureof the sole, and are held in normal position by springs 29. The centertool is pivotally mounted upon the lower end of the rod 23, so that itsoperating surface may conform to the longitudinal curvature of the sole.7

During the operation of the compressing tools upon the sole the head 22is reciprocatedthrough a bell crank lever 30, one arm of which isconnected by a link 31 with the head, and the other arm of which is con-..nected by a link 32 and pivotally supported downward movement of thehead, and acts to increase the pressure of the tool upon the sole.Immediately after the center tool engages the sole, the two side toolsengage the marginal portions of the sole, and then during the continueddownward movement of the head 22 the springs 27 and 28 yield to allowthe head to move downward with relation to the tools, and act toincrease the pressure of'the tools upon the sole during the continueddownward movement of the head. The downward movement of the head withrelation to the tool carrying rods.25

' and 26, after the downward movement of the tools has'been arrested bytheir engagement with the sole, moves th indicated in Figs. 8 and '9. IThus the tools are actuated to repeatedly apply pressure ,to the solesubstantially perpendicular to the surface being operated upon, and the.

tools transversely outward over the margin of the sole, as

their pivots so that their working surfaces automatically conform to thecurvature of the sole at the point of operation. By reason of thelaterally outward movement of the side tools as they are repeatedlypressed of the sole are moved simultaneously outward in oppositedirections, and therefore the lateral strains produced by the action ofthe tools are balanced, and each side of the sole is held fromdistortion while the other side is being operated upon. At the same timethe center tool is acting upon the center portion of the sole so thatthe sole is actu-' .ately shaped and brought into position against thelast. The force with which each tool is pressed against the sole isdetermined by the spring acting upon the rod which carries the tool, andtherefore the pressure and rubbing action exerted by each tool isunaffected by the resistance offered by the sole to the other tool ortools.

The leveling roll 21 is arranged back of the leveling tools so thatitactsupon the sole immediately after the tools have acted upon it, andapplies to the compressed and 'laterally stretched sole a longitudinallyprogressive pressure which removes any irregularities formed by thecompressing and rubbing tools, and finally shapes and finishes thebottom of the sole. The leveling roll is mounted in a yoke 36 formed onthe front end of a shaft 37, whichis mounted in a carriage 38, the shaftbeing so arranged that the lateral inclination of the roll 21 may bevaried .by turning the shaft in its hearings in the carriage 38. Thecarriage 38 is mounted to. move laterally in guiding ways formed in across-bar 39 of the bed 7, and in a transverse bracket 40 secured to theunder side of the bed (Figs. 2, 3 and 7). The front end of the carriage38 is provided with a roll 41 arranged to engage a bearing surface 42formed on a cross-bar 43 6f the bedv 7. At its rear end the rollcarrying shaft 37 is provided on opposite sides with recesses 44 whichareengaged by arms 45 of a yoke 46 pivoted on a reciprocating slide-bar47 By this connectionbetween the shaft 37 and the reciprocating bar 47,the shaft 37 and leveling roll 21 are caused to reciprocate with the bar47 By reason of this connection, also, the lateral movements of thecarriage 38'will cause the shaft 37 to be rocked to'tip the roll 21laterally in one direction or the other, according to the direction inwhich the shaft is moved from its normal position vertically above thebar 47 The lateral inclination of the leveling roll 21 is controlled bythe operator through an operating lever 48; the rear end of which isprovided with a gear segment 49 engaging a pinion 50 secured to a shaft51 which is mounted in the bed 7. The shaft 51 carries a spiral gear 52which engages a rack 53 formed on the carriage 38. When the lever 48 isin mid-position, as indicated in Figs. 2 and 3, the shaft 37 carryingthe leveling roll 21 is in mid-position vertically over thereciprocating bar 47. If the lever 48 is moved in either direction fromthe midposition, the movement imparted to the shaft 51 and spiral gear52 in one direction or the other, as the case may he, will move thecarriage 38 laterally toward one side or the other, thus carrying thepivotal axis about which the roll 21 turns laterally toward one side orthe other of the sole, and at the same time turning the shaft 37 aboutits axis to tip the roll in one direction or the other. By thus shiftingthe axis about which the roll -is tipped in varying its lateralinclination, the working surface of the roll, when the roll is in itsdifferent positions, remains in substantially the same vertical relationto the bed 7, so that the relation of the bed to the sole being operatedupon is not materially varied in tilting the roll to give it its extremelateral inclination when acting on the shank. The tilting of the rolldoes not, therefore, modify the relation of the compressing tools to thesole to such an extent as to interfere with their proper operation uponthe sole, as might be the case if the axis about which the roll istipped were not shifted in varying the lateral inclination of the roll.

The connections between the lever 48 and the leveling roll enable theoperator to readilv vary the lateral inclination of the roll bymanipulation of the lever, and at the same time the roll is locked bythe gear 52 and rack 53 against displacement under the pressure exertedthereon by the sole, so that the pressure is not transmitted through theconnections to the operating lever. No exertion on the part of theoperator, therefore, is required to maintain the leveling roll in theposition into which it is moved by manipulating the operating handle.The bar 47 is continuously reciprocated during the operation of theleveling roll upon the sole by the action of an eccentric 54 carrled bya continuously running shaft 55, and embraced by an eccentric rod 56,the front end of which is connected with the bar by a link 57.

During its advance movement the jack is advanced intermittently, and thecompressmg tools are actuated to operate upon the sole during theintervals between the advance movement of the jack. At the end ofpressing tools are thrown out ofoperation,

and the eccentric 35 which actuates the tool carrying head, isarrestedin position to hold the tool-carrying head atthe upper end ofits stroke,where the tools are held out' of engagement with the sole.The mechanism for intermittently advancing the jack consists of aratchet Wheel 58 secured to the crank shaft 6, and arrangedto be engagedby an operating pawl 59 and a stop pawl 60- (Figs. 1 and 4. Theoperating pawl 59 is reciprocated by means of an eccentric 61 secured toa shaft 62, and embraced by the upper end of the-pawl. The shaft 62 isrotated through a shaft-63, the lower end of which is connected withthe-shaft 62 by gearing 64, and the upper end of which is provided witha beveled gear-65 meshing with a gear '66 which is connected to rotatewith the eccentric 35 which operates the compressing tools. The pawls 59and 60 are normally held out of engagement with the ratchet wheel 58, bymeans of a guard which forces a side of the lever. The. leveris'operated to plate 67 formed'on the rear end of a lever 68, which ispivoted at 69 to the frame of the machine. The lever is held normally inposition "to retain the pawls out of engagement with the ratchet wheelbya spring 0, pin 71 against the lower sionof the treadle 13. When thejack is to be advanced, the operator movement of the treadle 79operatesthrough depresses the treadle 79 from the dotted line to thefull ine position, Fig. 1. The first downward the latch 72to depressthe'pawl guard'lever 68 and release the pawls, so that they will engagethe ratchetwheelfand then continued downward movement of the treadleorces the bed 7 which carries the leveling devices down so thatthe/leveling devices will operate properly upon the sole of the shoecarried by the Jack.

I At the same time that the jack operating pawls, are' thus thrown intooperation, the mechanism for rotating the eccentric 35, which operatesthe compressing tools, and for driving the gearing through which theoperating pawl 59 is reciprocated, is thrown into action.

The eccentric 35 and the pawl operating gearing is driven through afriction clutch, one member 80 of which is secured to the eccentric, andthe other member 81 of which is secured to the continuously rotatingeccentric 54 which vibrates the leveling roll. The eccentric 54andclutch member 81 are formed on a sleeve 82 which is connected to rotatewith and slide on the end of the continuously rotating shaft '55 (Fig.18.) Theysleeve 82 is operated to engage and dis- .engage the clutchformed by the members 80 and 81, by means ofa wedge 83 provided with twovertically extending arms having inclined surfaces arranged to engagecorresponding surfaces on a wedge block 84: which is mounted to slideonthe shaft 55. The wedge block- 84 is connected with the clutch sleeve 82by an arm 85, one end of is operated by its spring to engage the clutch,and thus throw the operating mechanism for the compressing tools and theintermittent jack operating mechanism into operation when the operatordepresses the treadle 79. At the same time the devices which maintainthe operating eccentric in normal position with the compressing toolsraised, are thrown out of operation. These devices consist of a cam disk89 connected to rotate with the clutch member 80 and eccentric 35, and alever 90 provided with a brake shoe 91 arranged to engage the surface ofthe cam disk.

The means for controlling and operating the clutch operating wedge andthe brake lever are shown in Figs. 3 and 10 to 17. The normal positionof the parts, when the jack is in its retracted position, and thecompressing tools are out of operation, is shown in Fig. 15. As hereshown, the brake shoe 91 on the-lever 90 is in engagement with a Ishoulder 92 on the cam disk 89, and the wedge 83 is held in its lowerpos ition.- The lower end of the wedge 88- is pivotally connected to anarm 93 secured to a shaft 945' (Fig. 10),. The shaft 94 also has securedto it a collar 95 which is provided with a lug 96, arranged to beengaged by a spring latch 1 97 pivoted on the brake lever 90. lVhen theparts are in the position of- Fig. 15, thelatch 97 is in engagement withthe lug 96, and the shaft 94 is held f rom movement under the influenceof the wedge operating spring 88 by the engagement of the brake leverwlth the cam 89. The means for disengaging the latch 97 from the lug 96,and'thus allowing the clutch operating wedge to be operated to I engagethe clutch, comprises a lever 98 provided at its lower end with a yoke,the arms of which are pivotally mounted on the shaft 94 on oppositesides of the collar 95 and brake lever. One arm of the yoke is providedwith a cam 99 arranged to engage a pin 100 on the pawl 97, and to forcethe pawl back out of engagement with the lug 96. The lever 98 is alsoprovided with a depending arm 101 which is connected by means of aspring 102 with the brake lever 90 in such manner that the spring tendsto swing the brake lever away from the cam 89. Such movement of thebrake lever is prevented by the engagement of the pawl 97 with the lug96 when the parts are in the position of Fig. 15. The lever 98 is alsoprovided with a rod 103 extending across from one arm of the yoke to theother, and arranged to engage a lug 101 projecting up from the hub ofthe brake lever. The upper end of the lever 98 is connected by means ofa link 105 with the end of an arm 106 of the lever 68 (Fig. 1). The linkis provided with a yielding connection 107 of common construction. a I

When the treadle 79 is depressed to throw into operation the jackfeeding pawls in the manner above described, the arm 106 of the lever 68is moved in adirection to force the upper end of the lever 98 toward theleft in Fig. 15. Asthe lever 98' is moved toward the left, the cam 99acts against the pin on the pawl 97, as indicated in Figs. 16 and 17,and disengagesthe pawl from the lug 96.

i This releases the shaft 9 1, so that the clutch operating wedge isforced upward to engage the clutch members 80 and 81, thus throwing themechanism which operates the compressing tools, and which operates thejack feeding pawl, into operation. The disengagement'of the pawl 97 fromthe lug 96 also releases the brake lever 90, so that the brake is thrownaway from the cam 89, and into the position indicated in Figs. 1 and 3.The jack is now intermittently advanced, and the compressing toolsoperated, until the leveling roll reaches the breast of the heel seat.

The operator then throws into operation the v mechanism for returningthe jack, and in so" doing he releases the lever 68, so that the pawlguard 67 is returned to normal position, throwing the jack operatingpawls-ou-t of operation, and the lever 98 is moved toward the right.Whenthe lever 98) is thus moved toward the. right, the ;bar 103 actingon the lug 104 lifts the brake lever, until the brake shoe engages theperiphery of the cam 89. Assuming that the brake shoe strikes the cam 89on the part 108, the upward movement of the lever will be arrestedbefore the pawl 97 has been raised far enough to engage the lug 96. Nowas the cam 89.

rotates, the brake shoewill ride over the shoulder 92 onthe cam, asindicated in Fig.

12, and then as the brake shoe rides on to the low part 109 of the cam,the pawl 97 will be raised, so that it will engage the lug 96 on theshaft 94, as indicated in Fig. 13. As the cam 89 continues to rotate,the brake shoe will ride over the rise 110 on the cam, and will bedepressed. As the brake lever is moved downward by the cam at this time,the pawl 97 by its engagement with the lug 96 will throw the clutchoperating wedge downward, thus disengaging the clutch members and 81.The momentum of the parts will carry the cam 89 into the positionindicated in Fig. 15, when the brake shoe acting against the shoulder 92will bring the clutch member 80 and eccentric 35 to rest, with thecompressing tools in their upper position.

The mechanism through which the operator reverses themovement of thejack, and throws the operating mechanism for the compressing tools andthe intermittent jack feeding mechanism out of operation, comprises alever 111 which is connected by means of a link 112 with a frame 113pivotally mounted on drive shaft 114:. The frame 113 carries two shafts115 and 116 driven in opposite directions from the shaft 111 throughabelt 117 which passes over pulleys on said shafts, and over an idlerpulley 118 mounted on the frame 113. The two shafts 115 and 116 areprovided with friction pulleys 119 and 120 arranged to he moved into andout of engagement with a friction drum 121 by the movements imparted tothe frame 113 through the lever 111. The friction drum 121 is secured ona shaft 122 which carries the pinion 123 arranged to engage a segmentalgear 124 secured to the crank shaft 6. The frame 113 is held normally inposition with both friction pulleys 119 and 120 out of engagement withthe drum 121, by springs 125 mounted on a rod 126 which is pivoted tothe frame 113, the springs being arranged on opposite sides of a fixedlug 127, and engaging nuts threaded on the rod. The lever 111 isconnected by means of a link 128 with a cam slide 129 mounted in thelever 68, and arranged to engage the latch rod 72 and disenga'ge'it fromthe lever when the operator moves the reversing lever 111 to reverse themovement of the jack.

When the operation of the compressing the friction pulley-119 intoengagement with the friction drum 121 so that the pulley and drumoperate to impart a return movement to the jack. After the mechanism forintermittently advancing the jack, and for op-.

erating the compressing tools, has been thrown out of operation by themovement of the lever 111, either continuous forward or backwardmovements may be imparted to the jack to move the sole back and forth'under the leveling roll by manipulating the lever to bring either thefriction pulley 119 or the-friction pulley 120 into engagement with thedrum 121. The operator may thus,

"through the lever 111 which controls the when the lever 79 is againdepressed-the.

mechanism for intermittentlyadvancing the jack, and the mechanism foroperating the compressing tools, will be thrown into operation.

Tn operating upon some styles of shoes it is not desirable to subjectall parts of the center of the sole to repeated compressions, and meansare therefore providedfor arresting the action of the center compressingtool during the operation of the compressing tools upon the sole. Asshown in Figs. 1,

2 and 3, this means comprises a stop bolt 130 arranged to be moved intoand out of the path of a lug 131 on the center toolcarrying rod 23. Thebolt 130 is yieldingly mounted in a slide 132 which 18 normally held inposition to retract the bolt by a spring 133. When the operation of thecenter tool is to be arrested, the operator forces in the slide 132,bringing the bolt 130 into the path of the lug 131, so that the boltprevents the downward movement-of the center tool during the downwardmovement of the tool-carrying head. So long as the bolt is in advancedposition, therefore, the action of the center tool will be arrested,while the side tools will continue to operate upon the sole. Whenever.the bolt, is returned to its normal position, the center tool, as wellas the side tools, will operate upon the sole.

ft is usually desirable that the center compressing tool be thrown outof operation when operating upon the shank of the sole, and itsoperation may therefore be conveniently controlled'by providing meanswhereby its operation is automatically arrested when the operator variesthe lateral inclination of the leveling roll for operation upon theshank of the sole.

In Figs. 19, 20, 21 and 22,11 have shown the form of mechanism for thusautomatically arresting the action of the center compressing tool whichI prefer to use. It is also desirable that the side compressing andlaterally rubbing tools should exert a greater pressure upon the solewhen operating upon the shank portion than when operating upon theforepart of the sole, and I have accordingly provided means for varyingthe pressure exerted by the said tools during their operation on thesole.- The means which I prefer to employ for this purpose is also shownin Figs. 19 to 22. As shown in these views, the stop bolt 134 forarresting the downward movement of the rod 23 which carries the centertool is arranged to be' moved into and out of the path of a lug 135 onthe rear side of the rod. The bolt is yieldingly mounted in a slide 136which is normally forced in a direction to withdraw the bolt from thepath of the lug 135 by a spring 137. v The rear end of the slide 136 isconnected to toggle levers 138,.one of which is pivoted .to the slideand the other of which is connected to a fixed pivot 139 on the bed 7.The pivotal connection between the toggle levers is connected by a link140 with the short arm of a bell crank lever 141, the other arm of whichextends down outside of the bed 7. The lower end of the bell crank leveris provided witha roll 1 42 arranged to engage a cam groove 143 in thelever 144 through which the operator varies the lateral inclination ofthe leveling roll 21. When the lever 144 is in mid-position and theleveling roll is properly inclined to act upon the forepart of the sole,the bolt 134 is in retracted position so that the center sole. Wheneverthe lever 144 is moved in tion of the roll'21 for operation upon theshank, the cam 143 will act upon the roll 142 to rock the lever 141 in adirection to straighten the toggle levers 138 and thus advance the bolt134 into position to arrest the operation of the center tool. Thepressure exerted by the side tools upon the sole is also controlledthrough the movements imparted to the bell crank lever 141 by the lever144 in varying the lateral inclination of the leveling roll foroperation upon the shank or forepart of the sole. The means foraccomplishing this comprises a slide 145 mounted to move vertically inthe toolcarrying head 22 and provided with laterally extending arms 146,the outer ends of which are slotted to embrace the tool-carrying rods 25and 26 and overlie the springs 27 and 28. The slide 145 is connected byeither direction to vary the lateral inclinaa link 147 with one arm of abell crank lever v The upper end of the pin carries a roll 153 arrangedto be engaged by the rear end of the lever 154 which is connected by alink 155 with the bell crank lever 141. When the bell crank lever 141 isoperated by the movement of the lever 144 to vary the lateralinclination of the leveling roll for operation on the shank of the sole,the lever 154 is depressed, thusyforcing down the pin 150 so that itengages the recess in the lug 152 so that the vertical arm of the bellcrank lever 148 is connected with the vertical arm of I the bell cranklever 30. The relative lengths of the arms of the bell crank levers 30and 148 are such that when the tool-carrying head is moved downward bythe movement of the bell crank lever 30 the slide 145 will be moveddownward more rapidly, thus compressing the springs 27 and 28 andincreasing the force with which the tools are pressed against the sole.When operating upon the forepart the bell crank lever 141 will hold thelever 154 in raised position, so that the pin 150 will be out ofengagement with the recess in the lug 152, and the bell crank lever 148will move idly as the toolcarrying head is reciprooated.

In Figs. 23 to 26 a construction is shown in which means'is provided forsmoothing andshaping the heel and heel seat during the levelingoperation. As shown in these views, the devices for smoothing andshaping the heel and shaping the heel seat comprise a series of hammersarranged to operate on the heel of a shoe supported on the jack. Thisseries of hammers comprises a hammer 156 arranged to operate upon theback of the heel, and two sets of hammers arranged to act upon theopposite sides ofthe heel, each set comprising two hammers 157 and 158.The hammer 156 is pivotally supported upon a rod 159 mounted in theupper end of a lever 160 and held yieldingly in advanced position in thelever by a spring The hammer" is held yieldingly in position in the endof the rod 159 by a spring 162, and the pivot for the hammer is soarranged that the operating surface of the hammer will automaticallyaccommodate itself to the curvature of the shoe in the direction of themovement of the hammer over the curvature of the heel; The lever 160 ispivotally mounted on the ack 1, and is provided at its lower end with aroll arranged to engage a cam 163 by which the lever is given a rapidoscillatory movement. The hammer carrying rod 159 is so mounted in theend of the lever 160 that the hammer is caused to strike a blow upon theback'of the heel close to the sole, and to then move ing faces willautomatically conform to the lateral and longitudinal curvature of thesides of the heel as the hammers engage and move over the surface of theheel. The hammer carrying rods are held yieldingly in advanced positionin the levers by springs 169, and the rods are so mounted in the leversthat when the levers are given an oscillatory movement the hammers arecaused to strike blows upon the sides of the heel close to the sole, andto then move vertically away from the heel seat while held in engagementwith the heel. This hammering and rubbing action shapes the heel andheel seat and smooths and finishes the sides of the heel.

Vibratory movements are imparted to the levers 166 and 167 to move thehammers toward and from the heel, and the levers are also givenvibratory movements to vary the position of the hammers 157 and 158longitudinally of the shoe, so that the entire surface of the heel willbe engaged and operated upon. The lever 166 is pivotally supported at170 so that its upper end may be moved toward and from the shoesupported on the jack, and may move laterally.

The lower end of the lever is provided with a roll 171 engagin a camgroove 172 formed in a cam drum 1 3, the cam groove being so formed thatit imparts rapid oscillatory movements to the lever to move its upperend toward and from the heel of the shoe supported on the jack. Thelower end of the lever 166 also carries rolls 174 arranged to engage camsurfaces 175 formed on the cam drum 173, and shaped to vibrate the upperend of the hammer carrying lever longitudinally of the shoe supported onthe jack. The cams are so shaped that the hammers will be shiftedlongitudinally of the heel of the shoe between successive blows, so thatsuccessive blows will be dealt at different points upon the heel, andthus the entire heel will be subjected to a hammering and rubbing actionby the series of hammers. The lever 167 carrying the hammers 157 and 158for acting upon the opposite sides of the heel is actuated in the samemanner by cams similar to cams 172 and 175.

The cams for operating the hammers which shape and smooth the heel andheel niaavir seat are secured upon a shaft 176 mounted in the from theshaft 2 on'which the jack l S'PlVObf ed. The shaft 2 is driven from theshaft 122 by means of a belt 17 8 assin'g over pulleys secured to theshafts. "hhus during the forward and backward movement of'the jack, thecam shaft 176 is rotated to'act'uate the hammers so that the heel seatisshaped and the heel smoothed during the operation of the levelingdevices upon the sole of the shoe supported on the jack.
